Preheat your oven to 350°F. Grease and flour a 9x5 inch loaf pan.

In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

In a large bowl, cream together the butter and sugar until light and fluffy.

Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

Gradually add the flour mixture to the butter mixture, mixing until just combined.

Fold in the raisins.

Pour the batter into the prepared pan and smooth the top with a spatula.

Bake for 55-60 minutes or until a toothpick inserted into the center of the cake comes out clean.

Allow the cake to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. Enjoy!
